If you intend to read ANSI or IBM labels, this **must** be set. Even if the volume is not ANSI labeled, you can set this to yes, and Susan will check the label type. Without this directive set to yes, Susan will assume that labels are of Susan type and will not check for ANSI or IBM labels. In other words, if there is a possibility of Susan encountering an ANSI/IBM label, you must set this to yes.
